通过Chef Server API获取配方列表

Question

I want to get the recipes that a cookbook contains, through chef-server-api. Following is the code I'm using for getting the cookbook list, individual cookbook details through the api :

require 'rubygems'
require 'chef/config'
require 'chef/log'
require 'chef/rest'
require 'chef/cookbook_version'

client_name = "admin"
signing_key_filename="c:/chef-repo/.chef/admin.pem"
server_url = "https://10.132.17.244:443"

rest = Chef::REST.new(server_url, client_name, signing_key_filename)
cookbooks = rest.get_rest("/cookbooks?all_versions")

cookbooks.keys.each do |name|
cookbook_versions = rest.get_rest("/cookbooks/#{name}")
print "#{name}\n"

cookbook_versions[name]["versions"].each do |cv|

version = cv["version"]
cookbook = rest.get_rest("/cookbooks/#{name}/#{version}")
 print "\t#{cookbook}\n"
 #parsed = JSON[cookbook]

end
end

The problem I'm facing is to get the recipe list from the 'cookbook' object. I tried parsing it to ruby hash and then read, but of no use. If I directly print the 'cookbook' variable, the output is something like the screenshot

I'm not able to get how to interpret the output I am getting by hitting the '/cookbooks/NAMEW/VERSION' endpoint, and get the recipes present in an individual cookbooks.

When using the Chef gem it automatically decodes some responses into Ruby objects for you. You can either use the object directly (specifically you want #recipe_filenames and then parse those to the cookbook_name::recipe_name format) or you could use a better API client like Chef-API or PyChef .

Need a ruby solution? The following example uses jq to filter the JSON resultset returned by knife:

$ knife cookbook show apache2 2.0.0 recipes -Fj | jq '.[]|.name'
"mod_cgi.rb"
"mod_proxy_http.rb"
"mod_proxy_html.rb"
"mod_access_compat.rb"
"mod_authz_dbd.rb"
"mod_proxy_express.rb"
